Abstract: Provided are a method for filling hydrogen gas into banks, configured so as to typically maintain high-pressure banks, thereby reducing time delays for supplying hydrogen gas to a second and subsequent FCV; and a hydrogen station. The hydrogen gas filling method and the hydrogen station are characterized by: filling hydrogen gas from a compressor into a bank (target bank) of which pressure is below the preset predetermined pressure; and if there are a plurality of other target banks, selecting as the filling bank a bank that may reach the filled state the fastest by being filled with hydrogen gas from the compressor.
